Patients complain that the implant parts loosen and shift. Even after a revision surgery, some patients experience nerve damage, tissue scarring, and reduced flexibility and mobility. Patients often find themselves still on pain medication months and years after the revision.
Knee implants are supposed to last 15 years. However, many patients with Zimmer NexGen CR-Flex replacements have had to undergo painful revision surgery within 3 years of the initial implant.
The NexGen CR-Flex device acts as an artificial connection between the femur and the tibia. Zimmer uses a porous fiber metal and cobalt-chromium-molybdenum alloy to make the NexGen CR-Flex. Orthopedic doctors initially thought the device would be revolutionary because it required no cement component.
The report stated that Dr. Richard A. Berger, a prominent orthopedic surgeon, now believes that Zimmer’s NexGen CR-Flex artificial knees are failing prematurely. Dr. Berger has released a scientific study proving this. In 2010, at a conference of the American Academy of Orthopaedic Surgeons, Dr. Berger and his colleagues revealed that 36% of patients with Zimmer NexGen CR-Flex had shown signs of loosening, pain and other problems within 2 years of receiving the implant. Dr. Berger’s data showed that nearly 9% of Zimmer NexGen CR-Flex patients needed revision surgery. Dr. Berger concluded that although Zimmer’s NexGen CR-Flex is still commercially available, it “should not be used for any patient.”
The situation sheds light on other problems, too. “Amid the booming use of artificial joints in the United States, the breakup between Dr. Berger and Zimmer highlights what experts say is a troubling situation for patients and doctors: when disputes arise about orthopedic implant safety, there are no independent referees or sources of information because no one tracks the performance of the devices,” the New York Times article stated.
